摘 要:This work deals with the modeling of the unsteady Newtonian fluid flow associated with an open cylindrical *** reservoir presents a hole on the right bottom *** volume variation,heat and mass transfers are *** unsteady governing equations are based on the conservation of mass and momentum.A finite volume technique is used to solve the non-dimensional equations and related boundary *** algebraic system of equations resulting from the discretization process are solved by means of the THOMAS *** pressure-velocity coupling,the SIMPLE algorithm(Semi Implicit Method for Pressure Linked Equations)is *** for laminar flow(Re1000),including the pressure and velocities profiles as well as the streamlines in the reservoir are ***,the effects of the D/d and H0/D ratios and Reynolds number Re on the fluid flow are *** is shown that the velocities and pressure depend essentially on the reservoir *** validate the model,the present results have been compared with Zhou et al.’s results,Poiseuille’s and Bernoulli’s exact solution.
